Is fourshiftplay.z13.web.core.windows.net legit or a scam?
Azure subdomain abused for phishing and tech support scams, flagged by Yandex Safebrowsing.
This is a malicious Azure subdomain used to host phishing and tech support scams. One antivirus engine flagged it as phishing, and security researchers have documented identical Azure endpoints delivering fake Microsoft alerts that push fraudulent phone numbers.
Score breakdown
These checks passed — but they don't clear the site. A clean antivirus result, valid SSL, and a calm server only mean it isn't hosting malware; they say nothing about whether the business is real. This verdict is based on the site's conduct and content, not a malware detection.
Analysis Summary
Website Preview
The site returned a server error when we tried to load it in our sandbox, so there was no page to capture. A working business almost always renders — treat this site as unverified.
We attempt a live render of every scanned site in a safe sandbox. This one couldn’t be reached — the failure itself is a signal, noted in the analysis below.
Visual analysis
We capture a fresh screenshot of the live page and ask a vision model to look for scam visual patterns — fake trust badges, countdown timers, overlay pop-ups, and visual clones of legitimate brands.

Intelligence
The URL sits on Microsoft's legitimate Azure static hosting service, which scammers routinely abuse because it is free and hard to block permanently. Yandex Safebrowsing detected phishing content on this specific subdomain. Malwarebytes and Broadcom have published reports showing attackers using the same web.core.windows.net pattern to serve fake virus alerts that trick users into calling paid support lines. The page itself failed to render during capture, consistent with attackers rotating or taking down individual scam instances quickly. No legitimate business operates under this subdomain, and the hosting model itself enables rapid abuse.

Safety FAQ
Common questions, answered directly from the scan data above — so the answers always reflect the latest verdict on this page.
- fourshiftplay.z13.web.core.windows.net is a dangerous scam site — avoid interacting with it. Our review tagged it for phishing and tech support scam. 1 of 92 security engines flag it (1 as outright malicious). The domain is 31 years old through MarkMonitor Inc.. This pattern matches throwaway sites built to take money or data and disappear.
- No — fourshiftplay.z13.web.core.windows.net scored just 6/100 on our trust scale, and we detected active threat indicators. We recommend avoiding it entirely: don't log in, pay, download anything, or connect a wallet.
- If you've already paid or handed over details on fourshiftplay.z13.web.core.windows.net, act quickly. 1) Contact your bank or card issuer immediately and ask to dispute the charge or open a chargeback — the sooner you act, the better your odds. 2) Report the site to the U.S. FTC at reportfraud.ftc.gov or the FBI's IC3 at ic3.gov, and in the UK to Action Fraud at actionfraud.police.uk. 3) If you entered a password, change it on fourshiftplay.z13.web.core.windows.net and anywhere you reused it, and turn on two-factor authentication. 4) Watch your bank and email for follow-up fraud, and keep screenshots as evidence.
- Often yes, if you act fast. Payments made by credit or debit card can frequently be reversed through a chargeback or dispute — contact your bank right away and explain it was a fraudulent site. Bank transfers and gift-card or voucher payments are much harder to recover, but you should still report them to your bank and to the FTC (reportfraud.ftc.gov) or Action Fraud (actionfraud.police.uk). Avoid any "refund" or "recovery" service that contacts you first — it's usually a follow-up scam.
- Just viewing a scam page is usually low-risk on an up-to-date browser — the real danger is what it asks you to DO (enter details, download a file, send money). If you downloaded anything, run a full antivirus scan and treat the file as untrusted. If you entered a password or card number, change the password everywhere you reused it and contact your bank.
- You can report fourshiftplay.z13.web.core.windows.net through several official channels: the U.S. FTC at reportfraud.ftc.gov, the FBI's Internet Crime Complaint Center (IC3) at ic3.gov, and — in the UK — Action Fraud at actionfraud.police.uk. You can also flag it to Google Safe Browsing (safebrowsing.google.com/safebrowsing/report_phish) so other browsers warn about it, and report it to the company being impersonated if there is one. Reporting helps get scam sites taken down faster.
- Modern scams are built to look convincing. A valid SSL padlock, a polished template, stock photos, fake reviews, and a trust badge can all be added in minutes and prove nothing about who runs the site. Scammers buy cheap domains, clone real designs, and copy legal pages wholesale. That's exactly why an automated review that checks the domain's age, hosting, blacklists, and behaviour — rather than just how the page looks — is more reliable than a first impression.
- Yes. 1 of 92 antivirus and blocklist engines in our malware network flagged fourshiftplay.z13.web.core.windows.net, 1 of them as outright malicious. Even a single detection from a reputable engine is a meaningful warning, and multiple detections rarely happen by accident.
- No — fourshiftplay.z13.web.core.windows.net is not currently on the major browser blocklist feeds that Chrome, Safari, Firefox, and Edge rely on. Note that blocklists can lag behind brand-new scam domains, so "not listed" is reassuring but not a guarantee on its own.
- fourshiftplay.z13.web.core.windows.net is 31 years old, registered on August 10, 1995 through MarkMonitor Inc.. A multi-year registration history is one of the stronger signals against a scam, though it's never a guarantee on its own — established domains can still be misused.
- fourshiftplay.z13.web.core.windows.net resolves to an IP operated by Microsoft Limited in US (Data Center/Web Hosting/Transit). Hosting location alone doesn't make a site good or bad — but hosting that doesn't match a brand's claimed country, or that sits on networks known for abuse, is one of the many signals we weigh alongside the verdict above.
- This report is a record of the scan run on July 22, 2026, and the verdict reflects that point in time. Scam sites change fast — they can go live, get flagged, or vanish within days — so if you believe something about fourshiftplay.z13.web.core.windows.net has changed, MalwareTips staff can run a fresh scan that re-checks every signal from scratch and republishes an updated verdict.
